The mean of 6,10,11,x,12,y is 10. Also y is 7 more than x. Find the value of x and y.

If mean of 6,8,x,12,y,14 is 10 then

if 2x-2y=10 find the value of x-y

In the adjacent diagram, if n(U) = 125, y is two times of x and z is 10 more than x, then find the value of x, y and z.

If 3x - 2y = 12 and 6x + y = 9 , then find the values of x and y

If 10y=7x-4 and 12x+18y=1 . Find the value of 4x+6y and 8y-x .

If (x+y, 5) = (10, y-3), find the values of x and y.

If (x+y, 5) = (10, y-3), find the values of x and y.

If 4x+5y=10,5x+4y=17 then find the value of x+y and x-y .
